Using fMRI brain imaging, scientists found three main areas stimulated by colour: V1, an area in the ventral occipital lobe, specifically the lingual gyrus, which was designated as human V4, or hV4, and another area located anteriorly in the fusiform gyrus, designated as V4α.
Neuromelanin gives specific brain sections, such as the substantia nigra or the locus coeruleus, distinct color. It is a type of melanin and similar to other forms of peripheral melanin. It is insoluble in organic compounds, and can be labeled by silver staining. It is called neuromelanin because of its function and the color change that ...
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Color processing in the extended V4 occurs in millimeter-sized color modules called globs. [30] [31] This is the part of the brain in which color is first processed into the full range of hues found in color space. [37] [30] [31] Anatomical studies have shown that neurons in extended V4 provide input to the inferior temporal lobe. "IT" cortex ...
If, for example, M cones could be excited alone, this would make the brain see an imaginary color greener than any physically possible green. Such a "hyper-green" color would be in the CIE 1931 color space chromaticity diagram in the blank area above the colored area and between the y axis and the line x+y=1. [citation needed]
As luck would have it, “a structure in the brain called the dorsal raphe nucleus is strongly activated in orgasm, and that region is very much associated with production and distribution of ...
Chemical signaling between neurons is mediated by neurotransmitters, neuropeptides, hormones, neuromodulators, and many other types of signaling molecules. Many neurological diseases arise due to an imbalance in the brain's neurochemistry. For example, in Parkinson's Disease, there is an imbalance in the brain's level of dopamine.
